Embodiment 1

[0145] The base station needs to allocate sidelink resources to the UE. The general process is as follows:

[0146] The UE first reports the sidelink UE information. If only broadcast and multicast are considered, then the sidelink UEinformation includes:

[0147]

[0148] But after the introduction of unicast, since the layer 2 id of the receiving UE is generated by itself and changes frequently, if the id of the layer 2 UE changes, what if it is reported to the base station? The present invention proposes the following solutions:

[0149] When the sender UE knows that the layer 2 id of the receiver UE has changed, it reports a new destination id list, or reports the destination id list through add and remove to save signaling. After receiving this information, the base station sends SLRB configuration information subsequently When using the new destination id.

[0150] When the sender UE establishes a connection with the receiver UE, obtain the layer 2 id information of...

Embodiment 2

[0159] For sidelink UE, a new BSR is introduced based on retransmission resource application: sidelink retransmission BSR.

[0160] The content of the retransmitted BSR includes: 1 or more HARQ process ids

[0161] Retransmission BSR trigger condition: NACK sent by the receiving UE is received

[0162] The Cancel condition for retransmitting the BSR includes any of the following:

[0163] If any HARQ process ID of the MAC entity has no data available for retransmission, the triggered Sidelink Retx BSR shall be cancelled.

[0164] If a certain HARQ process ID of the MAC entity has no data available for retransmission, the Sidelink Retx BSR associated with the process shall be cancelled.

[0165] When the Sidelink Retx BSR is included in the transmission of the MAC PDU, the Sidelink Retx BSR shall be canceled.

[0166] When the upper layer configures autonomous resource selection, all triggered Sidelink Retx BSRs shall be canceled.

[0167] further:

[0168] It is necessary...

Embodiment 3

[0172] If the configure grant is assigned to the broadcast service, then no corresponding ACK / NACK resources are allocated. If the unicast service is used, additional ACK / NACK resources need to be applied for, which is more complicated. Therefore, we propose that the base station is configured in the configure grant configuration. Carry the cast type information that can be used.

[0173] Further, the base station can configure whether each configure grant supports transmission of retransmission transport blocks. If supported, the configure grant can be used to transmit the configure grant, and the UE needs to determine whether to transmit a newly transmitted data packet or a retransmitted data packet on the configure grant, so as to determine its HARQ process id. So if the high priority LCID of the configure grant is limited, when the data packet of the LCID does not arrive, which priority is higher between the retransmission data packet and the newly transmitted data packet ...

Abstract

The present application proposes a UE information reporting method, an Internet of Vehicles resource configuration method and device, and a storage medium, the reporting method comprising: first userequipment (UE) acquires identification information of a second UE; and the first UE sends the identification information of the second UE before adjustment and the adjusted identification informationto network element equipment at a network side so as to report UE information. By the adoption of the UE information reporting method and device, UE information reporting and resource allocation processing based on a 5G straight-through link are achieved.

Description

technical field [0001] The present application relates to a wireless communication network, and in particular to a UE information reporting method, a vehicle networking resource configuration method and device, and a storage medium. Background technique [0002] The Internet of Vehicles refers to a system network composed of agreed communication protocols and data interaction standards. Communications based on the Internet of Vehicles are collectively referred to as vehicle-to-external information exchange (V2X, Vehicle to X) communication. Through V2X, vehicles and vehicles, vehicles and Wireless communication and information exchange can be carried out between pedestrians, vehicles, roadside equipment and the Internet. With the advancement of technology and the development of the automation industry, the V2X communication scenario has been further extended from the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) organization to 5G and has high...
